I have several customers email servers that I spamfilter and then forward filtered email. The problem servers are Exchange servers. We run Exchange inhouse for ourselves on our local network and it is never a problem. It seems that these customer Exchange servers usually require many spamfilter send attempts before mail can be transferred from the queue.  Is there a send from spamfilter.ini setting that I can adjust?   

If anyone has some ideas on how to reduce my connection timeouts I would love to hear from you.  My queue will stack up several hundred files at times before being cleared out.

Dwight,

From the logfile of Aug 10 you sent, we see that there's only 7 such errors for the whole day. They all appear to be caused by a timeout (~23seconds) occurring when SpamFilter tries to forward the mail to your Exchange server. 5 of them occurr between 00:02:43 and 00:04:00, with 3 of those in the span of 6 seconds at 00:02:43, 00:00:49 and 00:02:49.

The above 3 or 5 consecutive timeouts do seem to indicate a real problem in the network connection from SpamFilter to Excahnge. Can you confirm that there were no firewall timeouts if a firewall is between the servers, or that Exchange was 100% available? Sometimes backups or scheduled virus scans can slow down Exchange so much that it temporarily stops processing emails.

7 such events in a day is a very low number, and is very common to have a few delivery failures. Such emails will be redelivered on the next queue flush.

To be a problem, there should be several dozens or hundreds of such events. If this is so, if you can forward us a logfile that has this many failures we can try to find the problem.
